Comment 5 for bug 1835224

I think you misunderstand me a bit.

Yes gnome-terminal uses a systemd --user service to start a
terminal-server. This terminal-server is the parrent of all shells in
a gnome-terminal for this user.

The problem is systemd --user services are designed as per-user service
not per-session[0]. As I understand the Mailinglist, there ar no plans
to change this. So a systemd --user service isn't the right tool for
this architecture of a terminal and for any other programm which should
belong to a session. Thats why I say it's a bug in gnome-terminal not
in systemd.

That systemd has no per-session services is an other problem.
